Abstract: There lies a challenge to develop a technique of effectively establishing a direct communication link between client devices in a communication network. In some implementations, an associated STA is a client device which is associated with a particular access point (AP). A non-associated STA is a client device which is not associated with the AP. A tunneled probe request may be transmitted by an associated STA through the AP to be broadcast to other associated STAs. In some implementations, an active scan may be combined with a tunneled probe request in order to establish a communication link between an associated STA and a non-associated STA.

Abstract: Low-power transmitter and/or receiver devices are provided by sacrificing time and/or frequency diversity in exchange for lower power consumption. When channel conditions indicate that time and/or frequency spreading are unnecessary for transmissions, a transmitter may enter into a power-conservation mode in which transmissions are performed using a time gating scheme or a time repetition scheme. In the time gating scheme, symbols are transmitting just once, rather than a plurality of times, but with increased transmission power. In the time repetition scheme, copies of the same symbol are transmitted a plurality of times on the same frequency on different symbol transmission periods, instead of being retransmitted on different frequencies on different symbol transmission periods. Consequently, the symbol can be generated once and stored for subsequent retransmission, thereby allowing some of the transmitter/receiver chain components can be operated at a lower duty cycle or processing speed to conserve power.
Abstract translation: 通过牺牲时间和/或频率分集来提供低功率发射机和/或接收机设备，以换取更低的功耗。 当信道条件指示时间和/或频率扩展对于传输是不必要的时，发射机可以进入其中使用时间选通方案或时间重复方案执行传输的功率节约模式。 在时间选通方案中，符号只传输一次，而不是多次，但是传输功率增加。 在时间重复方案中，相同符号的副本在不同的符号传输周期上以相同频率发送多次，而不是在不同的符号传输周期上在不同的频率上重发。 因此，可以生成符号一次并存储以用于随后的重传，从而允许一些发送器/接收器链组件可以以较低的占空比或处理速度操作以节省功率。

Abstract: Systems and methods for extending header fields are disclosed. The header field may be extended without changing the current size of the header. Reserve bits may be used to indicate the use of an extended header and the extended header may be store in a variety of locations within the frame, including the frame payload or pad bits.
